OC-tool

POSIX shell script that builds an OpenCore EFI folder from an OpenCore config.plist

Can also be double-clicked in macOS Finder which will run as ./OC-tool -o

see either the OC-tool wiki pages for more detailed information
or the Docs/tool-changelog.md

• 0.7.4 marks the last update for this tool, if you want a tool that will be maintained going forwards, you can check out the replacement here https://github.com/rusty-bits/octool

---

Installation

git clone https://github.com/rusty-bits/OC-tool
cd OC-tool

copy your config.plist file into the INPUT folder, or copy and edit one of the sample plist files.

e.g. cp Docs/Sample.plist INPUT/config.plist

NOTE: If you use the Clone or download button OC-tool's files will be downloaded, but it won't be a repo and will error out when run since it can't update itself from github

Requirements

• access to a POSIX shell such as sh, bash, ksh, ash, or dash should all work. I myself use zsh with no problems, even though it's not strictly POSIX compliant.

It will also run on Windows under WSL or by using Git for Windows

That's it, nothing more is needed. OC-tool will make a working EFI folder by getting what it needs from the stable releases on Acidanthera's github or the daily build on Dortania if you so choose. git, grep, curl, cp, cut, tr, etc used by OC-tool should already exist on those shells.

Now, if you want OC-tool to build the latest from source you will need additional tools/dependencies, and as far as I know will have to use macOS as well. If there is a good way to run Xcode on Linux let me know ...

• To build from source Xcode with xcodebuild, nasm, and mtoc need to be installed and configured to run from the command line. You can build/install these yourself, or you can run the get-deps.sh in the .tool-files folder which uses code from acidanthera to get prebuilt dependencies.
  .tool-files/get-deps.sh while in the OC-tool directory
